All-purpose gas stove structure capable of increasing air intake thereof

Abstract

An all-purpose gas stove structure capable of increasing its air intake includes an all-purpose opening-covering case, an extended supporting frame, and at least one gas nozzle. The all-purpose opening-covering case includes an opening-covering case body for covering the heat source-receiving opening of a roasting/grilling device completely, and a gas controller with a gas operation unit for controlling the state of communication between gas input and output ends. The extended supporting frame is a box with a protective lid, is coupled to the inner side of the opening-covering case body at one end, and has a stove burner opening at the opposite end. The lateral walls of the protective lid are formed with vent holes. The gas nozzle is provided on the inner side of the stove burner opening. The all-purpose gas stove structure allows a ceramic roasting/grilling device to have a higher air intake and therefore produce higher heat.

What is claimed is: 
     
       1. An all-purpose gas stove structure capable of increasing an air intake thereof, comprising:
 an all-purpose opening-covering case comprising: 
 an opening-covering case body for covering a heat source-receiving opening of a roasting/grilling device completely; and 
 a gas controller provided in the opening-covering case body, the gas controller having: 
 a gas input end extending out of the opening-covering case body; 
 at least one gas output end; and 
 a gas operation unit, wherein the gas operation unit has an operation end provided on the opening-covering case body and configured to control a state of communication between the gas input end and the at least one gas output end; 
 an extended supporting frame formed as a box and provided with a protective lid, wherein the protective lid has lateral walls formed with a plurality of vent holes, and the extended supporting frame has one end coupled to an inner side of the opening-covering case body and an opposite end provided with a stove burner opening; and 
 at least one gas nozzle provided on an inner side of the stove burner opening and being in communication with the at least one gas output end; 
 wherein the opening-covering case body has a first width, the extended supporting frame has a second width, and the first width is N times the second width, with N being greater than or equal to 1.2 so as to accommodate a plurality of gas operation unit types. 
 
     
     
       2. The all-purpose gas stove structure of  claim 1 , wherein the opening-covering case body has one side formed as a curved structure. 
     
     
       3. The all-purpose gas stove structure of  claim 1 , wherein the gas operation unit comprises a low-heat control section for controlling an amount of gas output from a low-heat gas output end of the at least one gas output end of the gas controller to a low-heat gas nozzle of the at least one gas nozzle, and a high-heat control section for controlling an amount of gas output from a high-heat gas output end of the at least one gas output end of the gas controller to a high-heat gas nozzle of the at least one gas nozzle. 
     
     
       4. The all-purpose gas stove structure of  claim 1 , wherein the gas controller has a safety control valve for receiving a heat level signal from a heat sensor provided near the at least one gas nozzle and for cutting off gas output from the at least one gas output end when the heat level signal is lower than a control value. 
     
     
       5. The all-purpose gas stove structure of  claim 1 , wherein the opening-covering case body is further provided with an automatic ignition switch for controlling an automatic igniter in the opening-covering case body in order for an electronic ignition element provided at the at least one gas nozzle to carry out ignition at the at least one gas nozzle.
